不同颜色诱虫板对梨木虱诱杀效果比较

Comparison of Trapping Effect of Sticky Traps with Different Color on Psylla chinensis

利用不同颜色诱虫板对运城梨园梨木虱的诱杀效果进行了调查。结果表明,黄、白、蓝3种诱虫板的诱杀效果差异显著,其中,黄色诱虫板的诱杀效果最佳,梨木虱诱杀量是白色诱虫板的2.09倍,是蓝色诱虫板的5.86倍;白色诱虫板诱杀效果次之,而蓝色诱虫板诱杀到的梨木虱虫量最少。说明梨园悬挂诱虫板进行物理防控可行,建议在梨木虱大发生时,运城梨园中可悬挂黄色诱虫板,以降低园中梨木虱的虫口数量、减轻梨木虱的发生为害。

In this study,different color sticky traps were used to investigate the trapping effect for Psylla chinensis adults in Yuncheng area.The results showed that the sticky traps could trap a certain number of Psylla chinensis adults and played a role in physical control.According to statistical analysis,the trapping effects of yellow,white and blue three different color sticky traps were significant.Among them,the yellow traps had the highest amount,followed by white traps.The amount of Psylla chinensis adults by blue traps was the least.The amount of Psylla chinensis adults trapped by the yellow traps was 2.09 times that of the white trap,while the amount of Psylla chinensis adults trapped by the yellow traps was 5.86 times that of the blue trap.It is suggested that when the Psylla chinensis adults swarming outbreaks,the yellow traps can be hung in the Yuncheng area to reduce the number of Psylla chinensis and relieve the damage of Psylla chinensis.
